1. ## Fill in the blank

I have 45x40 floor space behind my 2nd row. 45" wheel well to well an 40" from back of 2nd row seat to rear gate. I kno I need to be a few inches from rear gate, so I figure 45x34 an I want to go 15" high. So is 45x34x15 rite or is there sum special ratio that needs to be used? I most likely will have my box built, it's jus 3-4 months down the way. An if I can get enough info by then I may make an attempt my self.

you need to pick a sub/s then figure out what size box they ( subs ) need.

3. ## Re: Fill in the blank

big scott's got the right idea. You build the box around the sub - at least it'd be easier to make a match that way. Figure out what subs you want, then figure out how much volume they each need for the type of enclosure you want to build, then build the box. There's no magic ratio, so long as it's not ten feet long by six inches high or something like that you should be good.

2 SoundQubed HDS315's....so how far back from the gate, 6" is enough?

That sounds right, but I don't run massive boxes like that, so someone's should confirm that number.

I think 6 would be the minimum.usually the same width as your port from what I've seen.

6 is where I had the best luck firing into a back gate. but since you didn't give us a vehicle...

2002 Ford Explorer....Did u have similar dimensions?

I had a GMC Jimmy and 6" was the magical number for me. best way to find out is trial and error. or shoot for 6" and go from there.

as far as your box dimensions, that is up to the subs and the amount of power to them. for 2 15s, id shoot for 6.5-8cuft if it was me.

I calculate 10cu net (45x32x15).... So smaller box u think? Ima start with a kicker zx1500 @ 2ohm thn with in a few months upgrade to a Q2200d @ .5ohm. After extra battery an HO alt. Am I goin about ths rite?

you have to factor in the port displacement and the subs displacement into your net box size. bigger could be better with the kicker amp, but with the sq2200, you are going to want to be a tad smaller to control the subs better.
